Cat bump

[Sam_Addison]

Hi.

Tonight as I was petting my male cat (4 years old and fixed) and his behind smelled. He is a long haired cat so I just wanted to make sure there wasn't something stuck in his hair. I discovered, right below his anus, a very mushy bump which when touched, he shakes a bit (almost like it either irritates or it excites him) and then he moves quickly away.

My question/worry is what could this possibly be? I have never noticed this before on him.

Thank you.

I'd suggest taking him to a vet if your concerned helath wise. can't be to careful with kitty's health, especially in certain regions...

It seems like skin. And whenever I touch it, his tail just goes ballistic. But he doesn't make any noise as if in pain.

Is this actually skin your feeling or a fur mat? If it's skin, it could be a hemorrhoid or cyst. Infections aren't mushy...
